Breaking: #97454 - Removed Link Browser hooks 

See forge#97454

Description 

The hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['LinkBrowser']['hooks'] with its two functions modifyLinkHandlers() and modifyAllowedItems() has been removed in favor of two new PSR-14 events \TYPO3\CMS\Backend\Controller\Event\ModifyLinkHandlersEvent and \TYPO3\CMS\Backend\Controller\Event\ModifyAllowedItemsEvent .

Impact 

Any hook implementation registered is not executed anymore in TYPO3 v12.0+. The extension scanner will report possible usages.

Affected Installations 

All TYPO3 installations using this hook in custom extension code.

Migration 

The hook is removed without deprecation in order to allow extensions to work with TYPO3 v11 (using the hook) and v12+ (using the new event).

Use the PSR-14 event as an improved replacement.
